The
4C81 is a low cost, low power consumption ARM based PC104-PCI CPU.
Designed for
wired or wireless networked applications, the 4C81 has two 10/100 baseT
Ethernet interfaces and a slot for a WI-FI card or other Mini-PCI
device. The 166 MHz CPU card consumes less than 2 watts
total from a single 5V supply, making Solar powered applications
practical. System resources include 32M or 64M of RAM and 32M to
128M of
NAND Flash memory and an RS-232 serial port.. The Ethernet
interfaces generates hardware TCP checksums allowing close to wire
speed routing through the 4C81. An optional on card 200K or 400K gate
Spartan3 FPGA with 32 bit local bus connection provides flexible user
I/O or a custom processing accelerator. The FPGA has 36 User I/O
pins available, 24 on a standard 50 pin header with interleaved
grounds. This connector is compatible with Mesa's Anything-IO expansion
cards
including the 7I30, 7I32, 7I33, 7I34, 7I37. The other FPGA I/O
connector provides 12 2.5V IO pins useable as 6 LVDS differential
pairs.
The model without FPGA has 36 5V tolerant I/O bits implemented in a
CPLD. The 4C81 can run Linux or NetBSD and has a jumper
selectable netboot option with NFS support to allow simple system debug
and software development. Applications include wired and wireless
routing, remote sensing and data aquisition, robotics, remote digital
I/O, motion control (With SoftDMC multi axis motion controller in
FPGA), web based remote control systems, antenna and camera pointing
systems.

The 4C62 is a high performance, high
integration 5X86 based PC/104-PLUS CPU card. The 4C62 has built-in SVGA
video that shares system memory (UMA) for low cost and high
performance.
The built-in SVGA video supports resolutions up to1024x768 by 24 bits
and video memory sizes from 512K to 4096K. The built-in SVGA video can
be disabled if desired. System memory can be 32M or
64M bytes, depending on 4C62 model. System memory is 64 bits wide for
high performance. A 32 to 128M byte IDE flash drive is built into the
4C62. Since the built-in flash drive is IDE compatible, no special
drivers are needed, regardless of operating system. An external IDE
interface is also provided. IDE interfaces are PCI based for high
performance. The on card PCI based 100 baseT ethernet provides network
connectivity. Standard I/O includes two 16C550 compatible RS-232 serial
ports. One of the ports can be configured for RS-485 type interface. A
bi-directional EPP/ECP/IEEE1284 compliant parallel port is provided, as
are a standard keyboard interface, a PS/2 type mouse interface and 2
USB
ports. The 4C62s watchdog timer and EEPROM BIOS setup storage plus
industrial temperature range capability make
the 4C62 well suited to embedded applications.

The 4C28 is a high integration, low power,
AT
compatible CPU implemented on the PC/104 bus. With the built-in 10BaseT
Ethernet interface, the 4C28 is ideally suited to network accessible
systems such as embedded web servers. The 4C28 has a 40 MHz 386SX
compatible CPU/chipset. System RAM can be 2, 4, or 8M bytes depending
on
model. The on card flash disk can be 8, or 16M bytes. Since the on card
flash drive is hardware IDE compatible, no special ROMS or drivers are
needed and the 4C28 supports most operating systems directly. A minimal
Linux installation that supports the 4C28 hardware and runs from the
flash drive is available from Mesa. The 4C28 BIOS EPROM uses flash
memory to allow field upgrades without physical access to the 4C28
card.
The BIOS can be configured to skip various device probes at startup,
speeding system boot-up in embedded applications. The 4C28 BIOS is
normally 128K bytes but can be extended to 256K bytes to accommodate
Datalight ROM-DOS or other built in operating systems. Datalight
ROM-DOS is available as a 4C28 option. On card 4C28 I/O includes two
16C550 type RS-232 serial ports, a bi-directional parallel port, a
floppy interface, an IDE interface, a high performance CS8900 based
10BaseT Ethernet interface and an 8 input 12 bit A-D converter. The
Ethernet interface has a remote, panel mount RJ-45 connector to
simplify system packaging. The second serial port can optionally be
configured for an RS-485 interface. Configuration storage is provided
by
an EEPROM, which is much more resistant to inadvertent corruption than
the battery backed CMOS configuration storage in a standard AT. 4C28
power consumption is 3W maximum with CPU running and down to .5 W with
CPU stopped. The RS-232 interface power is generated on card, so only
+5V power is required by the 4C28.

The 4C60 is a high performance, high
integration 5X86 based PC/104-PLUS CPU card. The 4C60 has built-in SVGA
video that shares system memory (UMA) for low cost and high
performance.
The built-in SVGA video supports resolutions up to1024x768 by 24 bits
and video memory sizes from 512K to 4096K. The built-in SVGA video can
be disabled if desired. System memory can be 8M or 32M bytes, depending
on 4C60 model. System memory is 64 bits wide for high performance. A 8M
or 16M byte IDE flash drive is built into the 4C60. Since the built-in
flash drive is IDE compatible, no special drivers are needed,
regardless of operating system. An external IDE interface is also
provided. IDE interfaces are PCI based for high performance. Standard
I/O include two 16C550 compatible RS-232 serial ports. One of the ports
can be configured for RS-485 type interface. A bi-directional
EPP/ECP/IEEE1284 compliant parallel port is provided, as are a standard
keyboard interface and PS/2 type mouse interface. The 4C60's watchdog
timer and EEPROM BIOS setup storage make the 4C60 well suited to
embedded applications. The 4C60 is a PC/104-PLUS card, meaning that in
addition to the standard PC/104 connector, a stackable PCI bus
connector
is provided. This allows interfacing to high performance PC/104-PLUS
peripherals. The 4C60 supports 3 bus mastering PC/104-PLUS cards or 4
slave PC/104-PLUS cards in addition to standard PC/104 peripheral
cards. The 4C60 can supply 3.3V power to PC/104- PLUS peripheral cards

The 4C61A is a high performance, high
integration 5X86 based PC/104 CPU card. The 4C61A has built-in SVGA
video that shares system memory (UMA) for low cost and high
performance.
The built-in SVGA video supports resolutions up to1024x768 by 24 bits
and video memory sizes from 512K to 4096K. The built-in SVGA video can
be disabled if desired. The 4C61A also supports TFT LCD displays,
useful when smaller displays are needed. System memory can be 32M or
64M bytes, depending on 4C61A model. System memory is 64 bits wide for
high performance. A 32 to 128M byte IDE flash drive is built into the
4C61A. Since the built-in flash drive is IDE compatible, no special
drivers are needed, regardless of operating system. An external IDE
interface is also provided. IDE interfaces are PCI based or high
performance. The on card PCI based 100 baseT ethernet provides network
connectivity. Standard I/O includes two 16C550 compatible RS-232 serial
